One of the significant products, which is delivered by the WAMBAF project is a mobile application developed to support the ditch inventorying and ditch management in forests. The system concept elaborated by all partners assumes server software and mobile application development. The user, after loading the files containing topographic information based on LiDAR data or other measurements, will acquire finished hydrological analysis output, which will be transferred directly to the mobile application. The application dedicated both to Android system and iOS system devices can help to find ditches in the field and also edit them outright on the device. The application and the system are dedicated mainly to forest owners who do not use GIS software in their everyday work. The application have multilingual and as simple as possible interface. In this regard the project has been implemented by Forest Research Institute, Poland.
